Most train services in and out of Wellington have resumed following a power fault on Thursday morning - but others remain suspended or have been cancelled.
On Thursday morning, a power fault caused an outage across all lines in and out of Wellington.
However, while that has since been resolved and most services have resumed, some have been cancelled.
According to Metlink Wellington, as of 8:15am, there are four services on the Hutt Valley line that have been cancelled as well as four on the Melling line and two on the Kapiti line.
There are also suspensions on those lines as well as the Johnsonville line. Train services from Johnsonville to Wellington will be replaced by buses between Ngaio and Wellington.
Delays of up to 27 minutes can also be expected for some services.
Many commuters vented their frustration on Twitter.
"Any more information. It is the first day of exams for many students," wrote one user, while another said: "Can you update please? People in the stations are walking to the cars and traffic in the SH2 is massive."
"This is becoming a common occurrence, maybe next month we could get a discount."
But one person found something to be happy about.
"Silver lining for me was an extra 10 minutes sleep on the train."
